I saw many slogans like this written on the side of the hills and mountains while cycling through the 甘孜 Tibetan autonomous prefecture in Sichuan province last spring:
This one says "感党恩 爱祖国 奔小康". Roughly translated: "Be grateful to the party, love your country, strive to be middle-class". I noticed it when I went with a friend to look for a valuable type of caterpillar fungus, called 虫草. There were also a large group of locals there, all looking to 奔小康 by finding the fungus and then selling it in the market (apparently, a single large piece can fetch potentially fetch several hundred RMB). Unfortunately, despite the encouragement of the mountainside slogan, my friend and I both left empty handed.
